How do I use my Cisco TelePresence MCU/IP VCR/IP GW product with an Asterisk registrar?

In order to register the Cisco TelePresence MCU/IP VCR/IP GW with Asterisk, the MCU/IP VCR/IP GW must be configured as an endpoint on the Asterisk Registrar. The Asterisk Reistrar runs on Linux and has a command line interface; therefore this article assumes that you are familiar with a Linux editor.

Open the sip.conf file and edit it as follows:

Create a new endpoint for the MCU/IP VCR/IP GW:

Set the username to match the Username field in Settings > SIP page on the MCU/IP VCR/IP GW

Set the password to match the Password field

If conference/recording registration is to be used, create a new endpoint for each conference/recording to be registered. Note that the MCU/IP VCR entry created in step 1 should be after these entries.

Set the username to match the Numeric IDs of the conferences (or auto attendants)/recordings on the MCU/IP VCR

Set the password to match the Password field in the Setting > Settings page

By default, Asterisk only supports audio. To enable video, add the line 'videosupport=yes' to the main body of sip.conf.

Enable the H.263 video codec - either by adding the line 'allow=h263' to the main body, or, for greater control, by adding it to the individual endpoint definitions (for those endpoints which you want to be able to send and recieve video).

In order for a SIP endpoint to be able to navigate the auto attendant, Asterisk has to be configured to use DTMF inband mode - either by adding the line 'dtmfmode=inband' to the main body, or, for greater control, by adding it to the individual endpoint definitions (for those endpoints which you want to be able to use DTMF).
